It's a form of demoralization. Deport on sight. Doesn't matter if they are legit user, bot, glowie, or shill. It's against the rules and need to be deported.

Edit: Hit that deport button, let the Mods decide.

Edit 2:They are very subtle at first. Don't engage, just deport. So far I saw 3 different ones first referring to the Bolsheviks, that lead to they are all jews, that lead to all jews are bad, that lead to dehumanizing comments. Couple anti-black comments saying "riggers get the rope" code word for -igger. Just beware of those types. Deport on sight, dont engage. Let the Mods decide.
